Within the overall preparedness related to nuclear and/or radiological accidents that lead to the
release of radionuclides to the environment with the consequent contamination of agricultural
areas, the priority of research for agricultural areas should then focus on the surrounding areas
of nuclear power plants that have higher probability of public exposure through the ingestion
pathway. The objective of this work was to create a rank order of priority of agricultural products
to be considered in assessing the effects of countermeasures, based on both economic value
and doses to the public. Additionally, the study describes relevant needs of radioecological
studies to improve short and long-terms dose assessments. Sixteen municipalities surrounding
the Brazilian Nuclear Power Central were analyzed for a contamination with 137Cs, considering
seasonal aspects related to agricultural practices in the Southeast Region of Brazil. Rank order
provided by considering economical aspects shows that there is a need for radioecological
research for some high value products, such as palmetto and sugar cane, and the need to
include in the current model more detailed description for some food items, such as eggs.
Combined rank criteria shows that main product within the considered area is milk and this shall
be the priority for the study of countermeasures for the ingestion pathway.
